COUNCIL BLUFFS, Iowa (AP) — A Council Bluffs man who shot his own mother while showing her his shotgun has been charged with a felony in the case.

The Daily Nonpareil reports that 20-year-old Seth Rennie has been charged with reckless use of a firearm resulting in serious injury. He posted $10,000 bond Friday and faces up to 10 years in prison if convicted.

Police say Rennie’s mother was visiting him on May 20 when he showed her his .410 shotgun and how to use it. Rennie told police he thought it was unloaded when he fired a shot, hitting his mother in the torso. She was taken to an Omaha, Nebraska, hospital with injuries, including a damaged liver. She told police the shooting was an accident.

Rennie’s next court hearing is July 18.
